I don't want to be "that guy" but I also don't want to be caught in the headlights if shit hits the fan (which it seems is inevitable). Anything to study to guide my thinking without going full-on bomb shelter?
On a serious note (though I really am getting the ranch) I would recommend reading John Robb's resilient communities blog - though his former defense-related work on Global Guerillas is brilliant too (he used to be a military strategist before realizing all these problems boil down to what I refer to above).
It's about resiliency. When things fail, and given our lack of investment in infrastructure, and coming challenges they will, it's important to be resilient and make sure those around you are too. After that it depends on how big you think the bottle neck is we all have to squeeze through to whatever is coming next. I worry it's quite narrow personally, but ymmv.
Finally... that edit to lifestyle is coming. It's just whether it's managed by you or you're managed by it.
Happy holidays.
